Definitions

  • the invention relates to a plant for the production of biogas from various organic waste materials from households, farms of agriculture and forestry and industrial and commercial enterprises (bioorganic residues) by anaerobic alkaline sludge digestion by various strains of methane bacteria with a digester and a supply line for the bioorganic residues ,
  • the invention also relates to a method for the production of biogas from bioorganic residues in which at least one naturally occurring digester different organic waste introduced and implemented according to the principle of anaerobic alkaline sludge digestion by means of various strains of methane bacteria in methane-containing biogas.
  • Methane-containing gas is also obtained, for example, from the mines of coal mines (mine gas).
  • Mine gas like biogas, also consists of the two main components, methane and carbon dioxide.
  • the mine gas escapes as a result of the loosening and pressure reduction of the seams.
  • German Offenlegungsschrift 1 758 628 the mine gas is extracted directly from the seams during exploitation by means of boreholes in order to obtain usable quantities of mine gas and at the same time to avoid explosive air-gas mixtures. Even if a mixture of methane and air is recovered due to the air contained in the shafts of the coal mine in operation, the proportion of methane at 80% is high enough for technical use.
  • DE-OS 4003487 describes a process for the stabilization of sludge introduced in a digester, in which a precursor contains a aerobic / anaerobic treatment takes place.
  • the disadvantage of this method is that in an aerobic pretreatment no biogas, but only carbon dioxide is formed.
  • German Offenlegungsschrift 1 758 628 a method for recovering mine gas from a previously partially exploited underground hard coal deposit by closing the access shafts and directing the mine gas from the mining sites to the surface is described.
  • the invention is therefore an object of the invention to provide a system and a method for the production of biogas from bio-organic residual materials, which the plant technical and energy costs and beyond the amount of work for the preparation of poorly biodegradable bio-organic residues for the implementation of large amounts of material in as an energy source utilizable methane-containing gas can be significantly reduced.
  • climate protection is to be taken into account and the greenhouse effect of carbon dioxide resulting from conventional combustion of the methane-containing gas or fossil fuels avoided.
  • a particularly positive effect of the invention is that as an energy source, the geothermal heat can be used to create a temperature level without additional heating to ensure optimal living and reaction conditions for the methane bacteria.
  • methane bacteria are very adaptable and have different strains, organic waste between 5 0 C and 70 0 C in the cryophilic range (below 10 0 C), in the mild zone (between 10 0 C and 28 0 C), in mesophilic (between 28 0 C and 42 0 C) and in the thermophilic temperature range (between 42 ° C and 70 0 C) converted into biogas. Only at a temperature above 70 0 C do the bacteria die off. Thus, these cavities are to be used as septic tanks in which, taking into account the self-heating of the bio-organic residual substances, a temperature in this temperature range is to be ensured in the course of the long-term reaction.
  • the plant according to the invention and also the method ensure the following triple use of renewable energies:
  • the biogas obtained can be supplied for energy production to known gas utilization facilities, such as combined heat and power plants and / or high-temperature fuel cells. Furthermore, the plant operating without danger to the environment can be combined with variants of the known mine gas production and can be coupled with known devices for the economic utilization of the recovered gas, in particular for the generation of electrical energy.
  • known gas utilization facilities such as combined heat and power plants and / or high-temperature fuel cells.
  • the invention provides such underground mines, which are intended only for a mine gas utilization to combine from the outset with the biogas production and a joint utilization in order to achieve a maximum energetic effect.
  • the Gas soungsanläge which consists of a disused underground mine with many remaining by previous degradation branched cavities, such as galleries, stretches and strut, uses as a digester at least two horizontally extending stretches and / or strut as well as blind tunnels. These be connected to one or more points by defined and gas-discharging holes together so that these gas-discharging bores all open in a located at the highest point of the mine gas storage tank. This eliminates dead zones in the mine.
  • the diameter of the holes to be prepared depends on the gas attack. Holes at the level of the lower sole are much smaller in diameter than near the surface. On the other hand, they should not be closed by penetrating residues.
  • dummy tunnels Since dummy tunnels have no connection to the earth's surface, they can be used as a gas collection chamber, for which they are provided with a subsequent drilling to the gas recovery station. Blind tunnels that are not intended for this use must also have a hole to connect them to the gas outlet and direct the methane-containing gases entering the gas recovery station.
  • the connecting tunnels shall be closed to allow better control of mine and biogas production. Only after complete filling of all cavities with bio-organic residues then other mines of the composite mine can be included in the inventive solution.
  • the arrangement of a gasometer is provided for the intermediate storage of the gas produced in a higher amount, in which the gas not used immediately after the gas extraction is filled at a slight overpressure of 20-50 millibar via supply lines from the gas collection container in the mine. Furthermore, even inactive, already flooded mines can be used according to the invention, in which the flooding water from the cavities can still be removed without major technical difficulties.
  • the biogas obtained in the biological process and located in the gas collection container or gas intermediate detector can either be mixed with the methane gas obtained in a possible combination with the mine gas production after removal of the carbon dioxide, fed directly into natural gas networks or separately via connecting lines for energy production in known gas utilization facilities, such as combined heat and power plants and / or high-temperature fuel cells are supplied.
  • gas utilization facilities such as combined heat and power plants and / or high-temperature fuel cells are supplied.
  • carbon dioxide can also be separated off from the gas mixture in the pressure or membrane process, liquefied and sent for recycling.
  • carbon dioxide is an effective fire extinguishing agent.
  • an advantageous embodiment of the invention provides for the organic waste to be brought into contact with seed sludge in the run-in stage. It is also beneficial to mix the added bioorganic residual substances with the digested sludge in the mine by injecting natural gas or biogas, so that the methane bacteria can be activated and produce biogas faster. The mixing with vaccine slurry can also be omitted if a longer start-up process is accepted. From the practice of mine gas production is known to suck the resulting methane gas before recycling. In the event of a malfunction in the system, a suddenly increased gas attack must be burned in a gas torch.

Abstract

L'invention concerne une installation et un procédé servant à produire du biogaz à partir de différents déchets organiques provenant des ménages, d'entreprises agricoles et forestières, ainsi que d'entreprises industrielles et commerciales (résidus bio-organiques), par digestion alcaline anaérobie des boues. L'invention vise notamment à réduire de manière significative le coût technique et énergétique et donc la quantité de travail nécessaire pour préparer des résidus bio-organiques même difficilement dégradables en vue de la transformation de grandes quantités de matière en gaz contenant du méthane utilisable comme source d'énergie. A cet effet, on utilise comme chambre de digestion des boues au moins deux cavités souterraines à peu près horizontales qui subsistent d'une exploitation antérieure d'une mine de houille abandonnée et on relie toutes les cavités de la mine en un ou plusieurs points par des forages définis évacuant les gaz de manière à faire déboucher tous ces forages dans un contenant collecteur de gaz se trouvant au point le plus haut de la mine. Selon l'invention, des résidus bio-organiques sont introduits, en grande quantité et sans fractionnement préalable, dans la chambre de digestion des boues où s'effectue la digestion des boues par des réactions de longue durée sans chauffage additionnel à un niveau de température donné compris entre 5 °C et 70 °C.
